Professor Krochta researched edible films and coatings, primarily from whey protein. The more basic aspects of his research are the effects of whey protein molecular structure and film composition on film formation, barrier properties, mechanical properties, color and gloss. The more applied aspects of his research involve formation of whey protein films as coatings on nuts to reduce oxidation, on chocolate to provide gloss, on high-moisture foods to inhibit microbial growth, on dried foods and cereals to reduce damage, and on paper and plastic to improve their barrier properties.
